What groups were segregated during World War 2?

During World War II, several groups faced segregation and discrimination, most notably Jews, who were targeted by the Nazis in the Holocaust. Other marginalized groups included Romani people, disabled individuals, and various ethnic minorities such as Slavic peoples. In the United States, African Americans experienced segregation in military service and society, facing discrimination in both the armed forces and on the home front.
